New Course Announcement: Verifying the Refrigerant Charge on a Residential Split-System Air Conditioner

If you’ve spent any time in the field as an HVAC technician, you know that refrigerant charge issues are one of the more common service calls you’ll run. A system that’s lost a significant amount of refrigerant is usually easy to spot, but what about the one that’s running a little off, not quite right, but not obviously broken? That’s where things can get tricky. That’s exactly what this course is designed to help you catch every time.

HeatSpring is excited to announce a new, practical course built specifically for HVAC technicians who want to build confidence and accuracy in refrigerant charging – Verifying the Refrigerant Charge on a Residential Split-System Air Conditioner taught by Joe Marchese.

What You’ll Learn

This course covers the full picture of refrigerant charge verification – from understanding why proper charging matters in the first place, to walking through the actual procedures you’ll use on the job. You’ll come away with a solid grasp of both the theory and the technique.

Course topics include:

• Why is it Important to Properly Charge an Air Conditioning System?
• Determining Proper Airflow – ABC (Air Before Charging)
• Methods of Refrigerant Charging
• Which Method to Use and Why?
• When to add refrigerant to a system
• Weighing in the charge
• Charging Non-TXV Systems
• Using a Superheat Calculator
• Charging a TXV System

Who This Course Is For

This course is designed for new technicians entering the HVAC field who want to develop solid foundational skills from the start. That said, experienced techs who want a structured refresher – or who’ve developed habits they want to double-check against industry standards – will find it valuable too.

The course puts a strong emphasis on safety protocols, proper tool usage, and the step-by-step procedures that keep both you and the equipment protected. Doing this work right matters, not just for customer satisfaction, but for system longevity, energy efficiency, and your own professional reputation.

Why Proper Charging Is One of the Most Important Skills You Can Have

Improperly charged systems can cause premature equipment failure, higher energy bills, and callbacks. A system running with too little refrigerant works harder to cool, stresses the compressor, and delivers poor comfort to the homeowner. Too much, and you’re looking at different problems – liquid slugging, inefficiency, and potential equipment damage.

The challenge is that diagnosis isn’t always straightforward. A system with a major refrigerant loss will show obvious symptoms. On the other hand, a system that’s lost 10-15% of its charge takes real skill and method to catch correctly. This course gives you the tools to find it every time.
